Module sparse_solve 

Sparse linear system solvers (CG, BiCGSTAB, preconditioned CG). Iterative solvers for sparse linear systems Ax = b.

Provides Conjugate Gradient (CG) for symmetric positive-definite systems, BiCGSTAB for general non-symmetric systems, and a Jacobi (diagonal) preconditioner for accelerating convergence.
